Setting HWTACACS timers
The device uses the following timers to control the communication with an HWTACACS server:
• Server response timeout timer (response-timeout)—Defines the HWTACACS request
retransmission interval. After sending an HWTACACS request (authentication, authorization, or
accounting request), the device starts the server response timeout timer. If the device receives no
response from the server before the timer expires, it resends the request.
• Primary server quiet timer (quiet)—Defines the duration to keep an unreachable primary server in
blocked state. If a primary server is not reachable, the device changes the server's status to blocked,
starts this timer for the server, and tries to communicate with the secondary server if the secondary
server is configured and in active state. After the primary server quiet timer expires, the device
changes the status of the primary server back to active.
• Real-time accounting timer (realtime-accounting)—Defines the interval at which the device sends
real-time accounting updates to the HWTACACS accounting server for online users. To implement
real-time accounting, the device must send periodically real-time accounting packets to the
accounting server for online users.
Consider the performance of the NAS and the HWTACACS server when you set the real-time accounting
interval. A shorter interval requires higher performance.
